[LG Optimus 2x] Ximo F. Verde:
On latest temasek, 617 stable and v20q nvrm. Just a couple of questions (sry if repeating, have been away for a long time).

A) Whats the most energy-efficient combo (kernel-ROM-nvrm) out there? Been noticing much higher drain than my (ancient now) sig configuration. Have to note that I'm talking about usage draining, standby seems ok.

B) Can I flash a different nvrm_daemon on top of the v20q without issues? Also, can i flash a different kernel (temasek's for example) on top of etana with no issues?

Thanx

PS. As i noted b4, i suffered no sod/bsod with 617 stable (and the rest above-mentioned)
[LG Optimus 2x] vadonka:
for me the best is the v20q nvrm daemon+temasek kang

in the latest beta im re enable the arm thumbee what is improve the battery life and dont have any negative sideeffect. i tested this many times.

disabled arm unwind and re enabled frame pointer. this two on some case cause bsod, as i see. not every phone not every time but maybe problem.

disable frame pointer dont provide any noticable improvement anyway.

swp emulate option remain disabled for a while now. this option cause the unfamous game compatibility issue with the planst and zombies and others.

so the latest beta only have a few change, but maybe help to avoid bsod.

who dont suffering bsod, no really need to update to the latest beta.
[LG Optimus 2x] franky_z:
did you try v20s nvrm daemon too? i´m on it now, would you suggest to go on v20q?
[LG Optimus 2x] vadonka:
yes i did, im not see any differences. you can use the v20s too.
[LG Optimus 2x] Infy_AsiX:
Thanks heaps vadonka. Latest beta fixed the constant shut off on gta3 brought by latest stable.
[LG Optimus 2x] Zorkman:
I flashed it, tried to reboot and the phone keeps hanging at the LG logo for me

I seem to be having the exact same problem as described here:

[LG Optimus 2x] Ximo F. Verde:
I enabled 3G/Data as I used to have back in the 2.xx versions of etana and temasek's 73 (or so). The drain even on standby is quite high (as mentioned at OP) with battery use reading 73% Cell Standby. I am absolutely positive that in the setup i had b4 those 2-3 months I had very low standby drain, even with 3G/data always on. Does this have to do with the 3.xx etana kernels? Also, and sorry for repeating myself, is it safe to flash temasek's kernel on top of it?
[LG Optimus 2x] franky_z:
i have no problem flashing daemon, but phone does not start when i make a ramhack via terminal. flashing back kernel without rh and phone starts again.

i tried 32mb and 48mb rh with newest beta kernel and 1206171648-ETaNa_OC-3.0.y.zip.

update: temasek kernel and rh works. perhaps it´s something with writing back kernel values? sorry, noop thoughts :o
[LG Optimus 2x] tonyp:
You could try to set the rh with the otf command.

Just an idea.
[LG Optimus 2x] franky_z:
heureka!!! it works!!! sometimes life can be so simple if you know the answer;)

thanks!:)
[LG Optimus 2x] vadonka:
changing ramhack only allowed with my otf script, because the kernel cmdline have some part what is needed for the otf. the old ramhack script wipe out this part and cause boot hang!

temasek kernel can be adjusted with the rh script, because that kernel dont need any other special cmdline part.

Hello vadonka, i still got some bsod an reboots with the latest beta kernel.

changelog for new beta?
[LG Optimus 2x] tomislav177:
Just to say that everything is working fine.

One question for everyone. I am using viber, with my bluetooth headset it just keeps disconnecting. So I decided to use handsfree with cable original from lg that came together with the phone.

What wierd is that sound is not working with handsfree. With normal headphones it works but. With handsfree it won't work.

Do you people have this problem or is it just my phone.

Sound is distorted and I also try one more set of handsfree and it is not working.

Is this kernel, or rom problem?

Thx
[LG Optimus 2x] Zorkman:
mine didn't turn off, it just "hanged"...

now on temasek 123 with no modified kernel, will try the next beta or stable when it arrives
[LG Optimus 2x] Infy_AsiX:

[LG Optimus 2x] N0r0:
hi,

i've got a problem and i'm not quite sure whether it's kernel-related. I installed TSF-Shell (a launcher), but when opening another app and returning to TSF by pressing home-button the app reloads. I guess it's killed in background in order to free the ram.

With running TSF i've got round 150 MB Ram not used. Is there a possibility to keep tsf in ram? Is it reated to LMK-Twesk?

kind regards and as always: a big thanks to all being involved :)
[LG Optimus 2x] Infy_AsiX:
I think I found what was causing my shutdowns in gta3. An incompatible app lux autobrightness reloading from background after killing it with tasker seemed to be the cause. Killing it with holding back prevents the problem. I wonder if it's related to other shutdowns people are experiencing. So for now i'm bsod problem free, yay.

On the note of battery life, things do seem good on new betas. I'm appalled at my phones capability though. It only manages 3 hours of screen on time. After doing some reading about kernel governors while setting my girlfriends Neo up, I started to investigate how our cpu scales.

It's a shame we can't have governors on our phone, because of all the choices and customisation in how the cpu frequency works. I noticed our phone hits max frequency very often on the slightest load. An example is screen scrolling, every movement hits max and seemingly a second long scroll will enable the second core. The amount of load it actually uses at the max frequency is often low so there's plenty of wasted idling. Sometimes it will stay constantly at max for several seconds working background tasks and only utilising 50%.

After some testing and constantly underclocking i've settled with 608khz with some otf tweaks. The otf minimises core2 activation and off delay, giving a smooth fast battery friendly approach. I honestly don't notice much slowdown and my battery life has increased 50%. It can handle 1080 video recording with mbps hack and most games. I'll put it to 1000khz for gta3 with full graphics.

Give it a try it's seriously smooth and fast with massive savings. The way the driver ramps to max frequency on every little load is amazingly inefficient. Here are some screenies

I only used to get 3 hours screen on time, I've gained 50%. Forgot to take a screenshot of percentages, but display percent is half what it used to be so that explains why the display percent was always so high; it counts cpu draw.

here are the settings
[LG Optimus 2x] pidocchio:
using those values makes your CPU1 going on earlier than on stock values, therefore your battery will last less.

great values using 1.2Ghz:

Min CPU1 On: 900Mhz

Max CPU1 Off: 950Mhz

CPU1 On Delay: 2 secs

CPU1 Off Delay: 1 sec
[LG Optimus 2x] Infy_AsiX:
You don't understand or didn't read what I wrote. The way the default cpu driver behaves is it ramps up to max immediately for almost everything. We're in desperate need of governors to modify that but we can't. Have a read about governors here http://xdaforums.com/showthread.php?t=1369817 it's very useful information all about them.

An efficient governor would set the frequency more appropriately and scale as required. Further enabling the second core when needed not automatically on almost every little task. We can't have that and the way ours scales is over aggressive and very conservative on disabling second core. So to adjust our min max values is all we can do within how it scales.

I've tried yours or 1ghz similarly and battery doesn't improve much and typically gets worse with overclock. If your sticking to that you might as well raise the values above 1ghz since vadonka raised it.

I even tried single core only at 1ghz and it gets choppy and slower than the two at 608. Simple maths shows why but single@1ghz battery also wasn't as much an improvement on battery. Since the driver keeps maxing and accomplishing the task slower and bottlenecked.
[LG Optimus 2x] darrenxes:
After installing latest stable kernel, can't boot after restart. Just did nvflash to recover stock rom
[LG Optimus 2x] extreme79:
with the latest 2-3 revision of kernel I've an issue with MP3 playback.. playing an mp3 cause a freeze of audio for many seconds, then the music start playing again for a little bit of seconds, then lock again.

I'm with latest stable kernel and latest Gueste 3.3 (cyano) and stock music player.

No issue with earlier version of the kernel. Could be related to it or it's just a case?
[LG Optimus 2x] pidocchio:
i do know what governors are and how kernel works in android, i can't understand how 608Mhz with the second core kicking in @560Mhz could be smoother and make the battery lasts longer than 1Ghz with the second core kicking in @816Mhz.

yes it can makes your battery lasts longer but it can't provide a smooth experience as a 1Ghz+ setting does.
[LG Optimus 2x] solrakk6:
when i choice active background (wallpaper).. after around 5 or 10 min and wake up my P990, the background is black and my active wallpaper was disappeared
[LG Optimus 2x] Infy_AsiX:
I didn't say it's smoother just still smooth. It's worth a try for the large increase in battery performance
[LG Optimus 2x] pidocchio:
i tried your settings and my second core was always on (obviously ^^), wasn't the second core activation the major cause of battery draining than single core with more hertz and voltage?

also i cannot stand the performance, it feels very choppy... as if that was not enough even with 1Ghz+ :P.
[LG Optimus 2x] Infy_AsiX:
It shouldn't be always on. Kind of mostly hits 1ghz the same when max set so. As I explained earlier single core running double the dual cores is shower, choppier and higher draining through longer processing time. You could use 800 instead but I don't think you're interested in anything but what you use.

Maybe if this worked it would easily show how the cpu scales. https://play.google.com/store/apps/details?id=com.bvalosek.cpuspy&hl=en It said the kernel is incompatible, is it possible vadonka?
[LG Optimus 2x] tonyp:
Has been asked several times, unfortunately there's currently no easy way to make it compatible to CPUSpy. That would be Nvidias fault.
[LG Optimus 2x] pidocchio:
i tried your settings because i want to make the most of this kernel, if i wasn't interested in anything but what i use i wouldn't even try.

here is what i tested:

608Mhz max cpu freq

508Mhz min cpu1 on freq

600Mhz max cpu1 off freq

my phone is constantly using both cores.

scrolling menu? both cores used

using any application? both cores used

only in idle it uses only the first core...
[LG Optimus 2x] rafcio:
H E L P !!!!!!

I installed the kernel, I made RH48 and after rebooting the white mark on LG phone turns off

How do I run a feed of the phone write it another kernel ???

Nvidia for sure is innocent. Cpu Spy runs on the Atrix and the Atrix shares the same tegra board....

[LG Optimus 2x] Infy_AsiX:
Min cpu1 higher, try 580. Here I took a couple of screenies

Here's how default settings look. The second peak is when I scroll up and down to show how it reacts.

Now with earlier settings. Second peak is scrolling again. It does hit dual core a couple of very brief times unnecessarily, I might try 750 delay for that. Still it shows what a load looks like and what idling looks like. Note it's hitting dual core again taking the screenshot.

Here are a couple of screens for interest. Exploiting a bug on lux autobrightness with a transparent theme gives me transparency to the live wallpaper demonstrating some extra load.

Anyway that's enough from me. Just thought i'd share a decent way of power saving that works for me.
[LG Optimus 2x] qgtxqj:
bsod with 0617 stable..back to 0523 which is most stable for me.

All work good on latest beta ;)
[LG Optimus 2x] RohanAJoshi:
plz anybody help.
[LG Optimus 2x] tomislav177:
Go in etana app and change values of min cpu1 off and on after that save and reboot your device.
[LG Optimus 2x] Infy_AsiX:
Had some after call bsod, shutdowns in gta3 and random resets. Back to last stable where I think it's ok. I'll report if it's no good
[LG Optimus 2x] extreme79:
I found "an issue" that can help who observe an high drain on battery.

If you enable the SQLite defrag option in Etana app, the phone kill :P your battery and the phone slow down a lot.

Disabling that option (disabled by default), the battery turn in a new life :) , the phone stay cool and the slow down disappear.
[LG Optimus 2x] pidocchio:
i found a good compromise between performance and power savings playing with Infy_AsiX previous values.

i came up with this:

816Mhz max cpu freq.

780Mhz min cpu1 on freq.

800Mhz max cpu1 off freq.

1 sec cpu1 on delay

500ms cpu1 off delay

try these settings and let me know what do you think of it.
[LG Optimus 2x] Istur:
Every time I use this kernel, I have a problem with the battery, the battery go up and down, for example I have 60% of battery and after a while the battery is 65% but it isn't in charge. I have used battery calibration but when I unplugged the phone, the battery level is 97% (not 100%)

How I can solve this problem?

I'm having this problem with the Cm7 kang (temasek rom) and also with the latest stock MIUI.

[LG Optimus 2x] grognaz:
do we need to disable compcache in cm with the default setting as well or only of set to ON?
[LG Optimus 2x] antec123:
for me i disable in CM settings
[LG Optimus 2x] grognaz:
oh well it still freezes randomly... gues i cant use these new versions for some reason...
[LG Optimus 2x] antec123:
what version you use non power save or power save??? and ram hack 32 version shared or traditional or base version??

i use base version once non power save. no random freeze with compcache disable on CM settings. but i do have freeze once with 32MB ramhack share version non power save(compcache disable on CM settings), i think because bugs that vodanka said before
[LG Optimus 2x] vadonka:
like i say the shared version maybe have some unknown issues. dont use it if you have random system freeze.

yes i know, but i like to try :D

[LG Optimus 2x] Medizinmann:
Hello Vadonka!

I tried the "normal" version with shared memory on my search when my cars new hands free unit wouldn't connect to my phones bluetooth.

I must say very impressive performance.:cool::):D

But I got again the annoying can't take call/can't hang up problem - and the usual solution setting ring delay up to 4000 didn't help - so I am back to the latest ironkrnL...;):)

BTW: In the end an update of the firmware of the hands free unit did the trick...:rolleyes:
[LG Optimus 2x] vadonka:
i and many other people notice that the "fix permissions" menu in the CWM or the rom manager will cause problem like this:

- unexpected application hang or force close (very hard to fix)

- battery status file unreadable (red '?' in the battery icon, need to delete batterystats.bin manually)

- wrong directory and file permissions (many file perm set to 0777 however this will causing many issues)

so DONT use this, it will not help but causing many issues!!
[LG Optimus 2x] lopiop:
does doing this fix permissions cause problems like this one, bcoz i did carry out the fix permissions

helo guys, im using CM7.2 Temasek KANG P204-41 with Vadonkas KANG kernel powersave, I seem to have this issue where locking my phone turns the screen off as usual but when attempting to turn it back on nothing happens. It hangs with the black screen. The message LEDs seem to continue to work but the only way to wake the phone up is by pulling the battery.

---------- Post added at 11:09 AM ---------- Previous post was at 11:06 AM ----------

also is there anything i can do about it besides reflashing
[LG Optimus 2x] vadonka:
i dont think so, its related to something else.
[LG Optimus 2x] s3nr1:
Using the 32mb powersave.

I'm getting a lot of radio crashes, settings->wireless settings->mobile networks is greyed out because of it and of course I can't get any service. A restart is needed.

I'm not sure what's causing this but a sure way to crash it is by going to the address book, going into a contact and clicking the green phone button to call. It will hang and a FC notice for .phone.

This seems to happen if the min frequency is at 216mhz(which is the default) in CM Performance settings.

Can anyone confirm this. This also happens with ironkrnl for me. I already tried baseband 218, 824 and now @10d 724, radio always crashes at some point when using 216mhz as the minimum, using the next lowest(503mhz) works.

The stock cm7 kernel in temaseks kangs works perfectly btw.

Edit: 503 crashes as well. ;p Ok I will try your suggestion below.
[LG Optimus 2x] vadonka:
Try to disable auto network time and use ntp based tine sync instead of the provider sync
[LG Optimus 2x] Shadowchaz:
Also try the normal version instead of powersave. I am using normal version with latest cm7 kang and its working fine.

I was getting radio crashes with miui now I'm on cm7 this seems more stable.
[LG Optimus 2x] stonebear:
In settings->cyanogen settings->performance->cpu I have lost the ability to change min and max CPU frequency after updating from 13/1/2012 (powersave) to 19/1/2012 (normal).

I also updated Temasek from 204-36 to 204-41.

Does the normal kernel not have OC ability?

edit

just noticed it says max cpu is 1000mhz, shouldn't it be 1100mmhz in normal version?
[LG Optimus 2x] buluba89:

[LG Optimus 2x] alakyr:
last kernel 2.32.y was stable with nice battery life? cause kernel 3 give me a lot of thermal issue then i was thinking about to instal the 2.32.y cause i don't have much time to spend on the phone....
[LG Optimus 2x] ilos:
no hot phone ?
[LG Optimus 2x] tonyp:
Yes then the 2.32.y kernel is a good choice.
[LG Optimus 2x] qgtxqj:
4 months ago, I installed kernel ver. Feb 22 (most people should had forget this version) into one P990 which used by a friend. Amazing thing is that she never met sod or shut off or other problem these days and I must say it is more stable than stock kernel and other kernels. of course, the problem with Feb 22 version is that one cannot play pvz etc because of incompatible issue.

I was suffering by sods with 3.0.y series and I think as a phone, most important is stable without bsod or shutoff. I has turn to Temasek OC kernel. during 2 days test, so far so good...

EDIT: had bsod with Temasek oc kernel too. wipe system and re-cwm MIUI with Temasek stock kernel for test.
[LG Optimus 2x] Infy_AsiX:
I'm back to temasek kernel. I'm trying max payne and keep getting shutdown. I even tried 23 may, it actually lasts longer but eventually shuts down as well. It's a shame because I like etana's power saving but it's unusable for stability.
[LG Optimus 2x] tomislav177:
Mate if you want to go other kernel great for you. Before you post in vadonka thread how you will now faster than a light speed go and flash other kernel think how hard is to develop such thing and is it polite to write such thing. Personally I have no problem with this kernel is working perfectly.
[LG Optimus 2x] McGiverGim:
Hi all. I wrote here to see if someone can help me.

I'm one of those who had reboots, bsod and shutdowns in froyo. With ginger official, the problems were gone, with stock kernel, spica or stefan kernel.

Now I'm on CM7, and I've reboots and hangs again (not too many, one every 2 days or so). I've tested Vadonka kernel (from 2012.06.08, with 324Mhz minimum) to see if it solves it but without luck.

Someone can help me? What can I try to solve this problem? A like CM7 but maybe I will be forced to return to stock...

Thanks in advance! I'm sure I'm not the first who had this problem, but searching at the thread I've not found the solution.

Regards!
